Tips: What advantages does the RDDLZ oval gear flow sensor have over ordinary flow sensors?
Compared with ordinary turbine or paddle-type sensors, the RDDLZ oval gear flow sensor offers ±5% high accuracy that is not easily affected by turbulence or viscosity. Its full-brass valve body (equipped with stainless steel components) ensures excellent durability, pressure resistance, and wear resistance—performance far superior to that of plastic housings. The imported Hall effect sensor provides stable and consistent pulse signals, guaranteeing reliable data output. In addition, it works well with water, oil, and other viscous liquids, making it more versatile than standard sensors limited to clean water. With its robust design and long service life, it is particularly suitable for harsh industrial environments such as petrochemical plants, refineries, and lubricant plants.
